Ok, basically im making my own wiring harness and I want to make sure im put 12v power (switch, when the key is turned on) on the right pins.

On AEM list (of what is what) I have "Ignition switch//Ignition switch//Input//Dedicated

Is this what need 12v power to turn the EMS on when I turn the key?


Also, it have 2: MFI switched power//12v//input//Dedicated im confused as to what the MFI input do? and are they the ones that need power to turn the EMS on?

This is for a 1313(u) AEM EMS I really appreciate the help
